Bridging wireless nic for kvm guests

[C. L. Martinez]

Hi all,

 I am trying to setup a bridge with a wireless nic (USB) only. I have
followed the following steps:
https://wiki.debian.org/BridgeNetworkConnections, but it doesn't works
in my ubuntu server 14.04.

 How can I bridge a wireless usb nic for kvm guests?? I need to use
this bridge fro three guests. For this reason, I can't use usb
passthrough.

 Thanks.
